Title: Damping force regulating hydraulic buffer
Inventor: WATANABE SEI
IPC: F16F9/44
Filed: 1990-01-20
Abstract: PURPOSE:To enable regulation to the optimum damping force according to the travel state, road surface status, and the like by making a selection among communicating passages of different passage areas by a shutter so as to change damping force generated in the high speed region of a piston, thereby regulating the damping force in the high speed region. CONSTITUTION:At the time of an expansion stroke, damping force is regulated by switching a by-pass passage 30 and making a selection among orifices 24-26 provided at the by-pass passage 30. At the time of a compression stroke, damping force can be regulated by making a selection among compression-side passages 13-15 of different passage areas by a compression-side shutter 32. Damping force at the time of the compression stroke and that at the time of expansion stroke can be thereby regulated independenty, so that the freedom of setting a damping force characteristic is heightened in large degree in comparison with the conuentional way, and therefore the damping force of an optimum characteristic can be generated according to the travel state of a vehicle, the road surface status, and the like.

Title: Motor unit which can be operated at high speed
Inventor: IBU GERIIN
IPC: H02P8/02
Filed: 1986-01-23
Abstract: In order to increase the maximum functioning speed of a stepping motor (1), with which a control circuit (2) is associated, it is equipped with a coil (5), the resistance and the self-inductance of which have values which are lower than the optimum values which they should have in order that the output of this motor has a maximum value when it is supplied by continuous drive pulses of given voltage and of an optimum duration which corresponds to this voltage and to the optimum values of the resistance and of the inductance of the coil. Furthermore, in order to avoid the motor not having this maximum value or roughly this value when the motor functions at low speed, the latter is then controlled by drive impulses of the same voltage and of the same duration as the continuous impulses but chopped. <IMAGE>

IPC: G01S7/02
Filed: 1984-01-25
Abstract: PURPOSE:To always search for a target on the horizontal by putting a target detecting sensor in searching operation in the horizontal direction detected by a horizon sensor. CONSTITUTION:The horizon direction is detected by the horizon sensor 24 and a horizontal search signal is generated by a search signal generator 23 by using its horizon detection signal to drive a torque 22; and the sensor 20 which is mounted on a gimbals 21 to detect a target 1 is put in searching operation in the horizon direction.

IPC: G03G21/00
Filed: 1994-02-03
Abstract: PURPOSE:To attain optimum image processing for each original by discriminating an original with projection from an original without projection. CONSTITUTION:A projection sensor 208a keeps an on-state longer by a timer difference t1 than an output of other projection sensors 208b-208e depending on a shape of an original 300. In this case, a controller 100 reads the output of each signal and discriminates a type of an original with projection based on a timing of a change in ON/OFF of each signal and on the time difference t1. In order to prevent mis-sensing, the reading by the sensors 208 to sense a tail end of the original is implemented for plural number of times for a period not looking over the tail end by the controller 100 and when outputs of the sensors 208b = 208e are consecutive for a known number of times, the sensing of a projection SP1 is ensured. As a result, the type of the original with projection is discriminated by sensing the output of each of the sensors 208.

Abstract: PURPOSE: To facilitate a split range control by offsetting the influence from a voltage Ve, while floating the emitter potential of a transistor receptive of the output of an operational amplifier by the voltage Ve, thereby to simplify a main circuit.  
     CONSTITUTION: The emitter potential of an NPN transistor 8 is made to float by the voltage level Ve of a negative power source 7 through a resistor RE. The emitter potential is divided by means of resistors R 1  and R 2  and is fed negatively to the opposite phase input terminal of an operational amplifier 3. The voltage Ve is divided by means of resistors R 3  and R 4  and fed to the correct phase input terminal of the amplifier 3. By the relationship of R 1  = R 3  and R 2  = R 4 , the influence from the voltage Ve is offset. As a result, the voltage Ve does not appear at the output so that an output current IO accurately proportional to the input voltage E i  can be obtained.
